I'm trying to create delivery order for each warehouse in sale order line
from where can get value of 'picking_type_id' of the delivery order?

class SaleOrder(models.Model):
    _inherit = 'sale.order'
    @api.model
    def action_confirm(self):
        res = super(SaleOrder, self)
        oreders = res.order_line
        for loc in oreders.mapped('warehous_id'):
            line = oreders.filtered(lambda o: o.warehous_id.id == loc.id)
            picking_vals = {
                    'origin': res.name,
                    'partner_id': res.partner_shipping_id.id,
                    'location_id': loc.lot_stock_id.id,
                    'location_dest_id': res.partner_shipping_id.property_stock_customer.id,
                    'picking_type_id':loc.out_type_id.id,

I used the following fields but it deoesn't work correctly
